The building regulations are coded by subject and run from part A to P, Part L refers to thermal efficiency standards and affects insulation and heat loss.
What’s New?
The amended regulations on energy efficiency are now in effect — and as Douglas Adams said, “Don’t Panic”.
| Element | 2006 U-value | New value |
| Roof | 0.16 | 0.15 |
| Wall | 0.3 | 0.2 |
| Floor | 0.22 | 0.15 |
| Windows | 1.8 | 1.6 |
| Doors | 1.8 | 1.8 |
| Permeability | 10m³/hr | 7.5m³/hr

As with all Government documents, the paperwork surrounding the new Building Regulations is daunting – around 600 pages of it – but actually it all boils down to two main points: the method of measurement shifts from elemental U-values to actual CO2 emissions and all domestic buildings need to show a 25% improvement in CO2 emissions over the 2006 standard.
